ATTACH M ENT FOR DYE-VATS.

SPECIFICATION forming part of Letters Patent No. 333,157, dated December29,-1885 Application filed July 6, 1885.

ric is wound from one upon another roller and back again untilsufficiently treated by the mixture, and thereafter the fabric is pulledoff from the roller last to receive it, and is deposited in a box, oristaken from the roller by a machine called a padder, it acting to foldthe goods.

While the fabric is first being run into the vat and wound upon one ofthe rollers, as Well as when the fabric is being finally removed fromone of the rolls into the padding-machine, it is necessary, in order'toprevent accident to the fabric, that an operator guide the fabric byhand.

In accordance with my invention the fabric, to enable it to be moreuniformly subjected to the die mixture or mordant, is taken from aroller or beam mounted upon a horse provided with wheels, the said horsebeing run into position next one end and locked in place at the end ofthe vat of the jigger,- and from the roller of the horse the fabric isled into the liquid or mixture and wound upon one of the'rollers of thejigger, and thereafter the fabricis rewound upon asecond roller of thejigger, the rewinding from one to the other roller of the jiggercontinuing as many times as may be deemed necessary, that dependingsomewhat upon the dye or mordant being used, and finally the fabric istaken from the last roller of the jigger to receive it and wound uponthe roller of the horse, the latter being secured to the end of the vat,and at the same time, if desired, a second piece of fabric may beintroduced into the vat and its liquid and be applied to the then emptyroller of the jigger, the said fabric being supplied from a roller on asecond horse. The horse employed to hold Serial No. 170,727. (No model.)

the roller to receive the fabric from the jigger is locked in train withthe jigger, and one end of the shaft of the roll on the horse is engagedwith a gear, which is rotated by a second gear then temporarily clutchedto the shaft, which drives the jigger-roller, the said shaft oppositeeach jigger-roller having upon it a bevelgear, which may be eitherclutched to the said shaft, so as to be rotated in unison with it, andthus rotate one or the other of the jigger-rolls, or be left loose onthe said shaft to permit the jigger-roll in operative connection withinit to be rotated only by the pull of the cloth.

My invention consists, essentially, in a vat, and two rollers havinggears on their shafts, and a horse having a-roller, the shaft of whichis provided with a gear and locking devices to retain the horse and vatrigidlyin position with relation to each other, combined with a shaftprovided with gears, and with clutches to rotate the said gears inunison with the said shaft or to permit them to remain at rest, thegears on the said shaft, when rotated by the said clutches, driving therolls, substantially as willbe described.

Figure 1 in plan view represents a jigger and horse and means foroperating the several rollers thereof in accordance with my invention,the fabric being shown by full lines as being removed to the horse; andFig. 2 is a right-hand elevation of only one side of the machine,looking at it in the direction of the arrow thereon.

keep the fabric immersed in the mordant or A their shafts A A mounted inusual bearings on usual stands, a a and having friction-pul leys A A",the uprights A, the carrier-roller A, the bevel'gears B B, respectively,on the shafts A A*, the main rotating shaft B the double-endedclutch-hub B splined on the said shaft and made longitudinally movablethereon by the shipper-fork B on a rock-shaft, B operated by a handle,B, and the two bevel-gears O O, loose on the said shaft B but restrainedfrom longitudinal movement on the said shaft by fingers C or it may bein other usual or equivalent manner, are all substantially as usual, andnot herein claimed.

The double-ended clutch-hub is ne ver in en- The vat A, the bottomrolls, a a, therein, to

other dye liquid or mixture, the cloth rolls A i gagement with both thegears O G at the same time, and consequently when one or the other ofthe rolls A or A is being rotated positively the other is left free tobe rotated only by the pull of the fabric f, as it is being drawntherefrom by the positively-rotated roller.

The devices so far described constitute what is called a jigger. At the.end of the vat of thejigger I have placed a horse, D, it con sisting. ash rein shown, of a base, D, uprights D", and wheels D the horse at itstop containing bearings for the reception of the roller E on a shaft, E,one end of the said shaft (see Fig. 1) being of irregular shape, andpreferably tapering, so as to enter a correspondingly-shaped socket inthe hub of a bevel-gear, F, having its bearing E on or part of the frameF, projected beyond the vat, and in case two vats are used in the sameseries connecting the two vats together, the latter plan being shown inthe accompanying drawings. The bevel-gear F is engaged by a bevelgear,G, mounted loosely on the shaft B", but provided at the end of its hubwith clutchteeth to be engaged by the teeth of a clutching-hub, G,spliued upon the shaft B and provided with an annular groove, which isen, tered by pins of a forked arm, 0, of a rock-f1 shaft, 0 having ahand-lever, 0 by which to move the said hub longitudinally on the saidshaft, to engage the gearG and rotate it'with the said shaft to turn thegear F and the roller E when desired, or to withdraw the clutchhub Gfrom engagement therewith when it is desired to leave the roller E to beturned in its bearingsas, for instance, when the fabric on the saidroller is to be taken therefrom and wound upon a roller in a second vat,A", or into the vat A, the drawings showing only a part of the saidsecond vat.

When fabric is being wound from one to the other of the rolls A A itpasses under the vat-rolls a a, as shown by dotted lines; but the fabrichaving been sufficiently treated, the same being, it is supposed, asherein shown, wound upon the roller A, is 1 ed up over the carrier rollA and the end of the fabric is joined to the roller E of the horse D,the gear 0 being nnclutched and running loose on the shaft 13 The horseD, to enable it to be used in train, as shown and described, has to belocked in place,.and as a means for such purpose I have provided hooksH, pivoted at H on the vat-frame, and engaging eyes H on the horse,but-instead of the said locking devices I might use any other equivalentmeans, such, for instance, as a bar, (1, engaging hooks d 11 as shown bydotted lines. This horse is removably held at the end of the vat, sothat the roll of fabric thereon may be readily and quickly rolled to anyother part of the mill to be placed in operative connection with anyother usual machinery--as, for instance, a cloth washing or a dryingmachine-the employment of the horse, as stated, saving very considerabletime and labor.

I have shown part of a second vat, A, intowhich the fabric may be takenfrom the roller E, the said second vat containing a different liquid ormixture and being provided with rollers such as described with relationto vat A, the said rollers having like actuating devices to rotate them.

I have shown mechanism for automatically rotating the roller E; but theemployment of the horse would be an improvement over ordinary methods ofhandling fabric at the jigger, even were the roller rotated by ahand-crank, as represented by dotted lines, Fig. 2.

I claim- 1. The jigger, its shaft B and a gear, G, and clutch-hub Gthereon, and a shipper to move the said clutch-hub, combined with ahorse and an adjustablelocking device to connect it with the jigger, anda roller, E, and gear F,

driven by the gear G, the hub of the gear F being connected with the endof the shaft of the roller of the horse, substantially as described.

2. The rollers A A of the jigger and the detachable horse provided witha roller, E,

combined with the rotating shaft B and with gearing, substantially asdescribed, for positively rotating the roller E in unison with one ofthe rollers of the jigger, whereby the cloth may be moved at will fromeither of the said rollers to the other, substantially as and for thepurpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WILLIAM H. RANKIN.
